Hi~ I go by the alias seraph online (and in person lol). I'm currently a founding software engineer at LunaBill (Y Combinator F25), working on automating medical-insurance call and claim pipelines. Previously, I was an MLE Intern at Foxconn , where I worked on latency optimization for multilingual voice agents.

I'm a final-year math-cs student at UC San Diego (UCSD). My interests lie in algorithm design and optimization, low-level AI systems (CUDA, Triton, PyTorch internals), and recommender systems. I have been daily driving Omarchy , an opinionated Arch Linux distro, and my preferred IDE is neovim + tmux.

Outside of academics, I'm a competitive programming enjoyer; in particular puzzles that force you to come up with elegant solutions (i.e. atcoder style problems). I also run a small (but active!) problem-solving server with 100+ members.

In my free time, I play rhythm games (my home page is strongly inspired by osu! ), piano, and all sorts of music such as jpop, kpop, rock, metal and classical. I also like hunting for good cafes and hidden gems.
